/**
 * Manages an AWS Lambda Alias. Use this resource to create an alias that points to a specific Lambda function version for traffic management and deployment strategies.
 *
 * For information about Lambda and how to use it, see [What is AWS Lambda?](http://docs.aws.amazon.com/lambda/latest/dg/welcome.html). For information about function aliases, see [CreateAlias](http://docs.aws.amazon.com/lambda/latest/dg/API_CreateAlias.html) and [AliasRoutingConfiguration](https://docs.aws.amazon.com/lambda/latest/dg/API_AliasRoutingConfiguration.html) in the API docs.
 *
 * ## Example Usage
 *
 * ### Basic Alias
 *
 * ```typescript
 * import * as pulumi from "@pulumi/pulumi";
 * import * as aws from "@pulumi/aws";
 *
 * const example = new aws.lambda.Alias("example", {
 *     name: "production",
 *     description: "Production environment alias",
 *     functionName: exampleAwsLambdaFunction.arn,
 *     functionVersion: "1",
 * });
 * ```
 *
 * ### Alias with Traffic Splitting
 *
 * ```typescript
 * import * as pulumi from "@pulumi/pulumi";
 * import * as aws from "@pulumi/aws";
 *
 * const example = new aws.lambda.Alias("example", {
 *     name: "staging",
 *     description: "Staging environment with traffic splitting",
 *     functionName: exampleAwsLambdaFunction.functionName,
 *     functionVersion: "2",
 *     routingConfig: {
 *         additionalVersionWeights: {
 *             "1": 0.1,
 *         },
 *     },
 * });
 * ```
 *
 * ### Blue-Green Deployment Alias
 *
 * ```typescript
 * import * as pulumi from "@pulumi/pulumi";
 * import * as aws from "@pulumi/aws";
 *
 * // Alias for gradual rollout
 * const example = new aws.lambda.Alias("example", {
 *     name: "live",
 *     description: "Live traffic with gradual rollout to new version",
 *     functionName: exampleAwsLambdaFunction.functionName,
 *     functionVersion: "5",
 *     routingConfig: {
 *         additionalVersionWeights: {
 *             "6": 0.05,
 *         },
 *     },
 * });
 * ```
 *
 * ### Development Alias
 *
 * ```typescript
 * import * as pulumi from "@pulumi/pulumi";
 * import * as aws from "@pulumi/aws";
 *
 * const example = new aws.lambda.Alias("example", {
 *     name: "dev",
 *     description: "Development environment - always points to latest",
 *     functionName: exampleAwsLambdaFunction.functionName,
 *     functionVersion: "$LATEST",
 * });
 * ```
 *
 * ## Import
 *
 * For backwards compatibility, the following legacy `pulumi import` command is also supported:
 *
 * ```sh
 * $ pulumi import aws:lambda/alias:Alias example example/production
 * ```
